Wiseco Chevy LS 4.145in Bore 1.165in CH -12.00 CC Piston Set

Forged from 2618 aluminum right here in the USA, these Wiseco pistons are built to handle the extreme demands of serious racing and heavy-duty performance builds for your Chevy LS engine. With a 4.145-inch bore and a 1.165-inch compression height, they're designed to work with specific engine configurations, featuring a -12.00cc dish volume that impacts your compression ratio. This isn't just about strength; it's about precision engineering for maximum output under pressure.

Wiseco has packed these pistons with features that matter when you're pushing your engine hard. You'll find precision ring grooves, an anti-detonation groove, and other features aimed at improving ring seal, which is crucial for both power and longevity. They also come with an ArmorGlide skirt coating. This coating helps reduce friction, makes operation quieter, and resists seizure, all vital for keeping your engine running smoothly when it's under severe stress. The fully machined crown ensures accuracy and consistency for each piston in the set.

This set includes eight pistons, complete with forced pin oiling to ensure the wrist pins stay well-lubricated, even in high-RPM, high-load situations. While these pistons are built for the toughest applications, please note they are not CARB approved and cannot be shipped to California. If you're building a high-performance LS engine for racing or severe duty, these Wiseco pistons are a solid choice for durability and performance.
